5.0 Oil Analysis

[427435]

I dumped the OEM oil at about 1800 miles for 5w-30 Mobil 1. Then changed again at about 7500 miles. Now the 3rd change at 15,000 miles. Results look good and could run the oil longer, but won't (warranty and my own caution).

Not sure where the iron is coming from as I thought the block was aluminum.

Sample looks good. The iron could be coming from cylinder liners, camshaft lobes, crankshaft journals, and oil pumps, basically any other steel parts sharing the engine oil. Check out the link below for more info. When you place the mouse pointer over the report an explanation will appear for each one.

Does the 5.0 have separate cylinder liners or are they an integral part of the aluminum block?

As for the crankshaft and cams, they should be hardened and little little material coming off them.

Has anyone else gotten an oil analysis on a Hyundai engine?
